摘要：This paper makes two contributions to the empirical literature on agglomeration economies. First, the paper uses a unique and rich database in conjunction with mapping software to measure the geographic extent of agglomerative externalities. Previous papers have been forced to assume that agglomeration economies are club goods that operate at a metropolitan scale. Second, the paper tests for the existence of organizational agglomeration economies of the kind studied qualitatively by Saxenian (...

摘要：It is often documented, based on autocorrelation, variance ratio, and power spectrum, that exchange rates approximately follow a martingale process. Because these data check serial uncorrelatedness rather than martingale difference, they may deliver misleading conclusions in favor of the martingale hypothesis when the test statistics are insignificant. In this paper, we explore whether there exists a gap between serial uncorrelatedness and martingale difference for exchange rate changes, and i...

摘要：Although bargaining is common in markets for heterogeneous goods, it has largely been ignored in the hedonic literature. In a break from that tradition, we establish sufficient conditions that permit one to identify the effect of buyer and seller bargaining on hedonic models. Our model is estimated using a previously overlooked feature of the American Housing Survey that permits us to observe characteristics of both buyers and sellers. Results suggest that household wealth, gender, and other d...

摘要：This paper calculates elasticities of demand for race groups in South Africa, government-revenue-maximizing tax rates, and excess burdens associated with taxes. A change in tax policy can be the political engine of income redistribution with appropriate taxes and subsidies on different commodities. This paper compares both semiparametric and parametric estimators with the censored least absolute deviation and censored maximum likelihood in calculating demand equations and elasticities. It is f...

摘要：Of all of the welfare reforms that were implemented during the 1990s, time limits may represent the single greatest break from past policy. This paper expands on what is known about this important welfare reform measure by exploiting the predictions from Grogger and Michalopoulos (2003) to estimate the effects of time limits on welfare use, employment, labor supply, earnings, and income among female-headed families. Results based on data from the March Current Population Survey suggest that ti...

摘要：Using U.S. input-output data for the period 1947-1996 and Dictionary of Occupational Titles skill scores, I find that U.S. exports have a high content in cognitive and interactive skills relative to imports, and a low content in motor skills. Moreover, the skill gap between exports and imports has widened over time. Imports are more capital- and equipment-intensive than exports, but the difference has fallen over time. By 1987 exports were more computer-intensive than imports. In contrast, tho...

摘要：We consider expectations of the form E[log y\x] = Sigma(j=1)(d) alpha(j) log x(j) as a good starting point for a more general analysis. We show why this naturally leads to the following flexible functional form: E[y\x] = f(Sigma(j=1)(d) h(j)(x(j))), where (f.) and the h(j)(.)'s are estimated by cubic splines. The main objective of this paper is to provide a straightforward method to estimate E[y\x]. We demonstrate the usefulness of this approach by estimating gasoline demand from the 1994 RTEC...

摘要：Stigma is a negative attribute of real estate acquired by environmental contamination and reflected in its value (Elliot-Jones, 1996). Using a model of neighborhood turnover with external economies, we show that both temporary stigma and long-term stigma are possible equilibrium outcomes after the discovery and cleanup of a hazardous waste site. The existence and duration of stigma are examined using hedonic price techniques with data from housing sales prices in Dallas County, Texas. We find ...

摘要：We develop an approach to identify and test for bid rigging in procurement auctions. First, we introduce a general auction model with asymmetric bidders. Second, we study the problem of identification in our model. We state a set of conditions that are both necessary and sufficient for a distribution of bids to be generated by a model with competitive bidding. Third, we discuss how to elicit a prior distribution over a firm's structural cost parameters from industry experts. Given this prior d...

摘要：Environmental regulation in the United States has undergone a slow evolution from command and control strategies towards market-based regulations. One such innovation is the Toxics Release Inventory (TRI), a regulation that requires polluting firms to publicly disclose information about their toxic emissions. The basic tenet of this regulation is that it corrects for informational asymmetries between polluters and households, allowing communities to pressure polluters to decrease their emissio...
